SPACING AND ALIGNING DEVICE.

Application filed November 24, 1925. Serial No. 71,145.

My invention relates in general to spacng'and aligning devices,

and my object is to provide an adjustable device of this class for use in laying the sheet metal angles in the construction of my floor described in my Patents No. 1,520,325 dated Dec. 23, 1924, and No. 1,539,988 dated June 2, 1925. Other objects will appear as the description progresses.

In my patented floor referred to above, sheet metal angles having longitudinal corrugations in their vertical legs and perforations and notches in their horizontal legs, as shown in Fig. 13, are bent as shown in Fig. 14 and nailed or otherwise secured to a base, as shown in Fig. 1. Concrete or other composition is deposited in the molds thus formed and leveled slightly above the tops of the sheet metal angles. The contraction incident to setting results in cracks whichuniformly follow the tops of the sheet metal angles. The sheet metal angles flexibly anchor each block to every adjacent block and rigidly anchor all the blocks to the base.

The sheet metal angles should be laid uniformly and properly aligned so that the molds will be uniform, therefore I have provided the present invention to facilitate the spacing and aligning of said sheet metal angles.

Fig. 1 represents a plan view showing the sheet metal angles secured to a base and the device in operative position; Fig. 2, an elevation of the device; Fig. 3, a plan view ofv Fig. 2; Fig. 4, a plan view of two devices connected, partly broken away; Fig. 5, an elevation of Fig. 4; Fig. 6, a plan and elevation of the left hand adjustable extension; Fig. 7 a plan, end and side elevation of the connecting member;'Fig. 8, a plan, end and side elevation of the right hand adjustable extension; Fig. 9, a plan, side and end elevation of a spacer arm; Fig. 10, an elevation of a bolt, washer and wing nut; Fig. 11, a side elevation of a fragment of my patented sheet metal angle; Fig. 12, a sectional view showing the angle in relation to the device; Fig. 13, a plan view of a sheet metal angle before bending horizontally, drawn to reduced scale; Fig. 14, a plan view of said angle after being bent into a component of a hexagonal mold.

' Although I have shown the preferred embodiment of my invention, I do not thereby limit myself to the precise form shownbut Wish it understood that various details of construction may be changed without departing from the claims. I contemplate constructing the device of metal as well asof wood but for convenience I describe it as constructed of wood.

The device comprises a narrow board 2, to one edge of which, cleats 3 are nailed or otherwise secured. The cleats 3 are'slightly thinner than the board 2, as shown in the end elevation in Figs. 3 and 12, so that the horizontal legs of the sheet metal angles 1, can be slipped under said cleats as shown in Figs. 1 and 12. Extension members 4 and 5, provided with slots 5 and 6 respectively, are slidably mounted at the ends of board 2 and clamped in position by bolts 7 and wing nuts 9. Cleats 10 and 11 are secured to extension members 4 and 5 respectively, and have the same function as cleats 3. A connecting member 12 is provided with a block 13 secured thereto and holes 14 and 15, and is connected to the ends of two boards 2 by bolts 7 extending through boards 2 and clamped by wing nuts 9. Movable spacer arms 17 are provided with dowel pins 18 which fit into holes in board 2, and

with blocks 19 and 20 which will be hereafter explained.

In use the device is disposed on the floor base in the manner shown in Fig. 1 and nails 21 are driven partly into the base, the heads being left so as to facilitate withdrawal. The spacer arms 17 are-then lifted until blocks 19 and 20 clear board 2 and swung to the positions shown in Figs. 3 and 4. In this position the blocks 19 and 20 rest on board 2. The function of block 20 is to hold the spacer arm 17 at right angles to the board while said spacer arm 17 is in the position shown in Fig. 1. When the device is moved to lay the next course of sheet metal angles 1, the spacer arms 17 are removed and the dowels 18 inserted in holes 22. For laying the "next'succeeding course of angles '1, the spacer arms 17 are changed back to Fig. 1.

If the board 2 be of the proper length to fitthe room, the extension members 4 and 5 are removed but if the board 2 be too short, the extension members are employed. If

the posit-ions shown in said extension members are adjusted equally, the side floor blocks Will be equal in Width. For large rooms, tWo or more devices may be connected in the manner shown in Figs. at and 5.

I claim 1. A device of the class described comrising a board having a straight edge; and cleats thinner than said board, spaced from each other and secured to the straight edge of said board; for the purposes set forth.

2. A device ofthe class described comprising a straight edged board, cleats thinner than said board spaced from each other and secured to the straight edge of said board, and longitudinally adjustable extension means mounted in the ends of said board.

3. A device of the class described comprising boards, each having a straight edge, disposed in longitudinal alignment, connecting means between said boards to bind them together; cleats thinner than said boards, spaced from each other and secured to said straight edges; for the purposes set forth.

4. A device of the class described comprising boards disposed in longitudinal alignment; connecting means between said boards; cleats thinner than said boards spaced from each other and secured to one edge of each board so that said cleats will be in alignment with each other; and longitudinally adjustable extension means mounted on the free ends of said boards; for the purposes set forth.
